</font><BR>
<BR><CENTER><B>Abstract</B></CENTER>
<P>The present specification discloses a flexible, adapable voucher gaming
     system having a LAN interconnecting a cashier terminal, a central
     voucher-record database server, one or more logical gaming controllers,
     and a plurality of player terminals in order to play games of chance at
     each player terminal. The system provides voucher printers at the cashier
     terminal and preferably at the player terminals as well. The vouchers
     include unique bar codes printed on the vouchers, and the bar codes are
     readable by scanners at the cashier terminal and at the player terminals.
     The player terminals are preferably adapted to provide the player with the
     option of receiving at least certain amounts of cash rather than a
     voucher, but to also ensure that at least a voucher is provided to the
     player in the event that the player terminal fails to dispense cash when
     earned by the player and payable to the player under the game rules at the
     player terminal.

Description</B></I></CENTER> <HR> <BR><BR>FIELD OF THE INVENTION
<BR><BR>This invention relates to games of chance.  More particularly, this invention relates to networked games of chance that a player may play by using or being awarded vouchers or tickets rather than cash.
<BR><BR>BACKGROUND OF THE INVENTION
<BR><BR>Casinos have long demanded cashless transaction systems for their games of chance.  The applicants have discovered that, however, gaming players often desire a simple, familiar method of transferring funds in and out of gaming devices without
inserting or withdrawing cash at the gaming devices themselves.
<BR><BR>Although other prior art systems also have provided the player with the ability to transfer funds from device to device via a printed voucher, they often have required cash funds to be inserted into the gaming devices to initiate game credit
deposits.  This is unworkable in certain jurisdictions as well as less than optimal for players who prefer not to deal with insertion of funds at the games themselves.
<BR><BR>Another problem is that the prior art voucher systems are usually inflexible.  For example, they typically do not provide for games of chance in the system to provide awards in one kind (such as by cash or by a particular product) as well as by
credit to the player through the voucher system.  This deprives the casino using such systems of the ability to generate excitement in the gaming environment, and thus stimulate the desire to engage in further play of the games, by, for example,
dispensing actual cash at the games or by providing awards of particular products to the game player.
<BR><BR>BRIEF SUMMARY OF THE INVENTION
<BR><BR>The applicants have invented a method and apparatus that can be, but need not necessarily be, cashless and does not require the player to insert cash at the gaming device itself.  The applicants' method and apparatus prints a unique voucher from
one of several different types of terminals on a gaming device network.  The cash voucher is accepted by the networked gaming devices (player terminals or PTs) in order to play the games on those networked devices (preferably games of chance).  The
method and apparatus preferably allows for the issuance of a voucher from a cashier terminal operated by a cashier (CT), an optional mobile cashier terminal (MCT), an optional automated cash exchange terminal (CET), or from a player terminal (PT).
<BR><BR>When a voucher is issued, a record of the voucher and its corresponding value are preferably recorded on a database in a separate computer called a player account server (PAS).  The voucher preferably may be redeemed for value at a CT or MCT. 
The voucher may also be used to enable the transfer of credits from the database to a PT, so that a player may elect to play at a different gaming device by generating a voucher on one PT and inserting it into another, without use of cash.
<BR><BR>Since the voucher identifies an item in the database, the apparatus and method can also be used, if desired by the casino, for the awarding of non-cash prizes, such as merchandise or other items of value at the CT or MCT or through a networked
point of sale system.
<BR><BR>As noted above, each voucher preferably has a unique and secure identification indicia printed on it in a machine readable code, preferably in a bar code.  The identification can be issued by a random number generator or by a combination of the
date, time, machine number, or other number wholly or partially encoded onto the voucher.  In the preferred embodiment the value of the voucher is used in the encoding algorithm, but is not included in the bar coded information.  This can allow
reasonable verification of an amount, but not regeneration of the amount.  This security method can also allow a ticket to be validated to a higher level of confidence using information not contained in the machine readable coding.
<BR><BR>There are other aspects of the invention that will become apparent as the specification proceeds.
<BR><BR>ADVANTAGES OF THE INVENTION
<BR><BR>It is an advantage of the present invention that it provides a voucher gaming system and method that are economical and relatively cost effective to implement.
<BR><BR>It is another advantage of the present invention that it provides a gaming system and method that allows the use of vouchers rather than cash to play games of chance.  This can allow a cashless mechanism that does not require player
identification, preregistration, or other inconvenient or expensive media.
<BR><BR>Yet another advantage is that the present gaming system and method can provide the option of presenting other forms of award, such as merchandise, entertainment, meals, special game or tournament play credits, or player club points to a player
other than cash or cash valued vouchers, such as products or services that may be verified through the networked gaming system, through a networked connection to a point of sale system or other system.
<BR><BR>Another advantage of the present invention is that it can be used to issue vouchers representing large jackpot awards that require unique administrative handling, while also leaving remaining player credits on the gaming device, thus permitting
continued play and profit for the gaming operator.
<BR><BR>A still further advantage of the present invention is that it can provide a fail safe award mechanism that ensures a player will receive a voucher award at the very least in the event of the inability of a gaming machine to dispense another type
of award, such as cash, to a player.
<BR><BR>An additional advantage of the present invention is that it can provide a system and method that are flexible and adaptable to provide a variety of types of awards under a varying system or use conditions.
<BR><BR>Another advantage of the invention is that it allows a method of voucher redemption by a cashier under conditions where certain network or database elements not fully operational.
<BR><BR>Another advantage of the invention is that it provides for a dual mode of operation, whereby the same hardware can function as a player terminal or as a cash exchange terminal, with an optional manual operation by a player required to change the
operating mode.
<BR><BR>Yet another advantage of the invention is that it allows for a cashier terminal to be mobile using a radio link for connection to the other elements of the system.
<BR><BR>Still yet another advantage of the invention is that it allows a dual mode of prize payout, whereby a given prize can be issued from a gaming device in a voucher or cash form.  This can be initiated by player selection or by one of several
circumstances, such as when a coin or coupon payout hopper is empty or a malfunction of one or more other devices interferes with the payout taking place.
<BR><BR>There are other advantages of the invention.  They will become apparent as the specification proceeds.  In this regard, it is to be understood that, with regard to the above-noted Brief Summary of the Invention and Advantages of the Invention,
the scope of the invention is to be determined by reference to the accompanying claims and not necessarily by whether the subject matter fulfills all aspects of the Brief Summary or Advantages stated above. <BR><BR>BRIEF DESCRIPTION OF THE DRAWINGS

drawer 38.
<BR><BR>Referring now to FIG. 4, an alternative embodiment of the CT 16 has a central computer 26 consisting of a Javelin model JAV-LGNPW D32 WIN with integral customer display 32, video display 30, and touch screen 37.  Mounted on the central computer
26 are conventional Ethernet ports (not shown) 27, optionally, for the MCT, a radio transmitter/receiver (Aironet), a hand held bar code reader 28 (Metrologic Model MS6720), ticket printer 34 (Transact Technology Series 700 Thermal Printer), audit
printer 35 (Epsom TM-U200PD Model 119D), and a cash and voucher drawer 38.
<BR><BR>As shown in FIG. 3, the CT central computer 26 for the CT 16 shown in FIG. 4 consists essentially of a PC running the Windows NT or Windows 95 or 98 operating system.  The central computer 26 has a standard PC motherboard 40 connected to and
supporting the operation of the bar code reader 28, the table video display 30, the tower or customer display 32, the audit printer 35, the voucher printer 34, the touchpad 37, the drawer 38, and the network comm ports 27.  The construction of the CT16,
in conformance with this specification, is well known to those skilled in the art.
<BR><BR>With reference now to FIG. 5, the applicants' preferred player terminal PT 20 includes a central PC or equivalent motherboard 42 connected to and supporting a visual display (Telco high resolution 19 inch) 44, push or game buttons 45, a
combination voucher and currency reader (JCM WBA 13SS) 46, conventional gaming network LAN input/output ports or communication interface 49, and ticket printer (Transact Technology Series 700 Thermal Printer) 43.  Optionally, the PT 20 may include a coin
dispenser (Akahi-Seiko) 47 in order to dispense cash awards.  The construction of the PT 20 in conjunction with this specification is well known to those skilled in the art.
<BR><BR>Referring now to FIGS. 2 and 4, the voucher printer 34 on the CT 16 prints, as shown in FIG. 6, a paper voucher 50.  Preferably, a similar type of voucher 50 can be printed by the ticket printer 34 as shown in FIGS. 2 and 4.
<BR><BR>Preferably, the voucher 50 reports the date and time that the voucher or ticket 50 was issued.  It also identifies the issuing device CT, MCT, CET, or PT ("VLT") that issued the ticket, and a ticket number.  The ticket 50 also states an amount or
face value of the ticket 50 when issued by the CT, MCT, CET, or PT as applicable.  Finally, the ticket 50 also includes a bar code 51 that has a variety of fields representing the above noted data stated on the face of the ticket 50.
<BR><BR>The bar code 51 also imbeds an encoded value, which is derived as a function of the information on the ticket, including the amount.  Since this field is compressed, the algorithm does not allow for the reverse calculation.  This value can also
be used to confirm that a ticket is being redeemed for the correct amount, because the algorithm can be recalculated and checked.  Such algorithms are well known to those skilled in the art; and the applicants believe that a wide number of such
techniques may be utilized equally well.  The ticket 50, thus contains information to provide for checking the authenticity of the ticket 50 as it is being used by the player in the present system.  This also provides a mechanism whereby a ticket may be
validated for redemption, even when access to the database is denied through network or other failure.
<BR><BR>With reference now to FIG. 7, a player initiates play in the present system and method usually by handing cash (or other form of remuneration or credit) to a cashier attending a CT or MCT.  The cashier enters the transaction into the CT through
the keyboard, and the CT generates a unique transaction code to be printed on a voucher as noted above in connection with the discussion of FIG. 6.  The CT then transmits the calculated transaction code and associated data (the time, date, amount
tendered by the player) to the PAS.  The PAS checks the validity of the information received from the CT, records the transaction code, amount of the voucher value and identifying data, and stores the information in the database.  The.  PAS then
transmits to the CT a confirmation of the validity of the code and stores all the information in a database record to be accessed by the unique transaction code.  Upon receiving the confirmation the CT prints the voucher, such as shown in FIG. 6.  The
cashier then hands the voucher to the player so that the player may take the voucher to commence playing games of chance on any one of the PTs on the network, as shown in FIG. 1.
<BR><BR>With reference now to FIG. 8, a player may initiate play in the system by inserting cash into a CET.  Multiple bills can be inserted until the player elects to print a voucher by pressing a button or touching a designated area on the CET touch
screen.  The CET prints a voucher of the type shown in FIG. 5.  The CET transmits to the PAS a record of the unique transaction number, the value of the voucher, the date and time of issue, and the identity of the CET.  The PAS will record this
information in the database and confirm the completion of the transaction to the CET.
<BR><BR>With the addition of a mode switch on a PT, a PT can be used to perform the function of a CET.  That is, PT can accept cash and print tickets when in CET mode, and then, when placed into a PT mode by depressing a mode button, accept vouchers,
issue vouchers, and conduct games of chance and provide awards as further provided herein for PT's elsewhere.
<BR><BR>Referring now to FIG. 9 a player may transfer credit from the database to a PT in order to play a game of chance on the PT.  The player inserts a voucher into the voucher receptacle in the voucher/ currency acceptor.  The PT reads the voucher's
bar code (51 in FIG. 6) and verifies an error free read.  The PT then retains the voucher temporarily in an escrow position and sends the voucher's bar code to the PT's processor, which forwards it to the PAS.  The PAS uses the transaction code to access
the database record maintained by the database on the PAS.  PAS then confirms the encoded information within the bar code against the related information maintained in the PAS database and thus confirms that the ticket is valid.  PAS then returns the
voucher amount from the PAS database to the PT and updates the status of the applicable PAS database record to indicate that the voucher has been paid.
<BR><BR>If PAS reports that the voucher is invalid, the voucher is not accepted and is backed out of the escrow position in the voucher reader assembly and returned to the player.  If, on the other hand the voucher is valid, the PT stacks the voucher
internally and credits the player with the amount from the associated PAS database record.  The player may then use the credited amount to initiate games of chance on the PT.
<BR><BR>With reference now to FIG. 10, when the player decides to terminate play on the PT, the player presses a button or touch screen area on the PT, which terminates play on the PT during an idle period, as is well understood by those skilled in the
art.  The PT then prints a new, second voucher and ejects it toward the player.  This second voucher is also of the type generally shown in FIG. 6.  With continuing reference to FIG. 10, this second voucher includes an associated second balance for the
player and second transaction code, based on the same type of data and encoding techniques described above for the first voucher issued to the player at the CT.  The PT also reports this second code and associated data (credit balance for the player,
date, time, and PT number) to the PAS, and the PAS confirms the data and updates the database record.  The PAS then notifies the player's PT that the new, second voucher has been recorded in the PAS database.
<BR><BR>With reference now to FIG. 11, the player may redeem the second voucher at the CT.  In doing so, the player hands the second voucher to the cashier at the CT, and the cashier scans the bar code on the second voucher with the bar code reader on
the CT.  The bar code reader interprets the bar code, and the CT then reads the bar code, including its encoded information and other associated data as noted above.  The CT then sends this transaction code and associated data to the PAS, and the PAS
checks validity of the code and data against the contents of the record for the transaction code in the PAS database and returns a status (and value of the voucher, if any) to the CT.  If the PAS reports that the data is invalid, the CT rejects the
voucher and reports the rejection on the CT table display.  If the PAS reports that the data is valid, the CT reports the amount of the credit due the player on the CT table display, and the cashier pays the player.
<BR><BR>Even under conditions of partial failure, applicants have discovered that it is highly desirable to be able to pay a player an amount due.  Accordingly, the method allows validation, even if access to the PAS is not possible by a CT or MCT, due
to network or other malfunction.  In that case, the CT or MCT locally validate the payment, retain a record of the transaction, and forwarding a record of the transaction to the PAS at a later time.  In order to accomplish the task, the CT or MCT, after
reading the bar code, prompt the cashier to enter the face amount of the voucher through a manual entry.  The CT or MCT then perform two checks.  First, the CT or MCT verify that the encoded information is consistent with all data on the bar code and the
amount, and then CT or MCT verify that the machine (CT or MCT as applicable) does not already have the particular ticket or voucher in the machine's local database (which would, if already in the local database, indicate that the particular voucher or
ticket has already been cashed).  If neither is true then the cashier is prompted to pay the customer, and the voucher record is retained in the local database of the CT or MCT, as applicable,for later transmission to the PAS.
<BR><BR>Referring now to FIG. 12, the PT alternatively provides cash awards of certain types and product or service awards based on certain predetermined or random outcomes on the PT.  For example, the PT is alternatively programmed to dispense cash only
up to a certain ceiling, and thereafter, pay all or a portion of such level-exceeding awards by issuance of an updated voucher or ticket to the player at the PT.
<BR><BR>Alternatively, or in addition, the PT may be programmed to provide awards of a service or product, rather than cash, upon the occurrence of certain outcomes at the PT.  In this event, the preferred PT may report such service or Product outcome on
an updated voucher issued to the player.
<BR><BR>As noted above, the PT reports such outcomes and additional vouchers to the PAS.  The PAS then records and stores the information reported on such additional vouchers so that the player may procure the proper award reflected in such additional
vouchers from the cashier at the CT.
<BR><BR>Alternatively, or in addition, the PT, if adapted to provide cash or other awards directly to the player from the PT or associated dispensing structure, may be programmed to determine when the PT or other dispensing structure has failed or is
unable to dispense dispense the appropriate award to the player.  In such event, the PT preferably reports the failure to the PAS and issues a suitable voucher or ticket to the player so that the player may then redeem the voucher for the proper award at
the CT or MCT, if present in the network.
<BR><BR>This voucher printing mechanism thus serves as a fail safe mechanism to ensure that the player procures the proper award with minimal if any frustration.  This in turn enhances the player's overall gaming experience and the likelihood that the
player will continue playing the game or return to the establishment to play games of chance at a later time or date.
<BR><BR>Alternatively or in addition, the PT may also include both a cash hopper and voucher printer and also be programmed, as shown in FIG. 13, to allow the player to elect between receipt of cash or a printed voucher reflecting the amount of an award
or credit balance on the PT.  The nomenclature for the program of FIG. 13 is as follows:
<BR><BR> PAYAMOUNT Player or customer credits to be paid.  JPVALUE Individual prize wins over this amount will be paid by  voucher.  PRFAILCOIN If printer fails, then pay up to this may be made by  coin.  CUSTCHOICE Provides the option to operator to
allow customer to  choose ticket or coin payment  LOCKUP LIMIT Value at which machine will "lock up," requiring  attendant, e.g., cashier at CT, to make prize payment  to the player.  MAXCOIN Maximum size payment that can be made in coins at  the PT.
<BR><BR>As explained above, the method and apparatus of the present invention may include a mobile CT apparatus ("MCT") mounted on the LAN and connected to the PAS through the HUB shown in FIG. 1.  One such mobile cashier terminal is manufactured and
sold by Sierra Design Group, Reno, Nev.  This mobile terminal consists of a unitary cart assembly and mounted within it: a voucher printer assembly (Transact Technology, of Wallingford, Conn., Series 700 Thermal Printer), a cash drawer with till, a spare
till, a bar code scanner assembly with base (Metrologic Model MS 6720), CPU with touch-screen display (Javelin Model JAV-LGUPW D32 WIN), power supply, 12V batteries, wireless LAN module with power supply (Airnet Remote), UPS without battery but with
inverter to invert the 12V DC power from the batteries into 120V AC power for the other components on the cart, six-outlet power strip, and battery charger.  The mobile terminal also utilizes a radio link, such as an Airnet Base Station and Remote.  When
used in the present apparatus and method, the Airnet Base Station is mounted on the LAN to perform wireless communications with the Airnet Remote mounted on the mobile terminal in a fashion well known to those skilled in the art.
<BR><BR>It is to be understood that the foregoing is a detailed description of the preferred embodiment and various alternatives and options in connection with the present invention and the preferred embodiment.  The scope of the invention, however, is
to be determined by reference to the following claims.
